A car’s engine is a complex system, and the BMW S65 is even more complex than most. The Catch Can Project was designed and engineered to help solve many of these complexities when engines are modified with something as small as a tune or as large as a supercharger system. For instance, when oil blow-by occurs, the engine is configured to recirculate the oil back into the engine. The factory oil separators are not able to keep up, or age over time and fail. This process can have detrimental effects, such as power loss, increased case pressure, and even poor fuel economy.
By replacing the oil separators (PCV system) with custom block off plates, the oil, unspent fuel, fluorocarbons, and gases are redirected through the catch can setup and not back through the intake system. This allows for a more precise burn of fuel, less back pressure in the crank case, and no build up on the throttle bodies, intake plenum, and valves.
OEM gaskets are used on the block off plates, so sourcing replacement gaskets is as easy as going to the dealer or any OEM parts supplier. The custom washer relocation bracket is a direct drop in and requires no modification. The basic kit also comes with the ESS relocation bracket in case you are supercharged or plan to be later. All hardware to install this kit is included and it installs in about an hour or less. Fully reversible with no modification needed to install.
These parts are all CNC machined and/or laser cut for precise fitment and come black anodized and powder coated to last for years.
This is designed to be a hardware kit, letting the end user decide what works best for them. Recommended: Nuke Performance .75L catch can and Radium 10AN swivel fittings (2 for NA or 3 for supercharged). Nuke Performance catch can and Radium fittings are not included.
